Periodic cleaning is cleaning performed at planned intervals rather than only in response to a spill, complaint or damage event.
What this means at your property
A commercial plan may include high ledges, carpets or areas not addressed during routine daily work. The right interval depends on use and observed condition. A calendar alone does not show whether a recurring moisture or residue problem has been corrected.
What should the schedule contain?
List the surfaces, method, access needs and person responsible for review. Record exceptions and recurring findings so they can prompt maintenance or investigation rather than being removed repeatedly without understanding their source.
